What cam should I get?

Think about the operating range on the .484" cam for a moment. With a 2,600 up operating range, this means that the engine will not pull the car and rpm under this starting rpm. It will move the car but without building rpm's rapidly and the torque #'s will also be slow to build. On the stock 273 4bbl cam, the operating range is about 600 to probably 5,000 rpms. This means that the car will launch or take off hard from 600 rpms and will build torque quickly and accelerate quickly. If for example, you had a 3,200 stall converter and 4.11:1 gears, you probably could get the .484" cam to work with the proper intake, headers and decent flowing heads. Incidentally, 2.02" intake valve heads will not work on 273 engines without notching the top of the cylinder bores. You should find out what gears you have and what transmission you have. The engine could have the 10.5:1 pistons or the 2 bbl 9.2:1 pistons and this is important info to know when selecting a cam. Aslo '67 was the last year of the closed chamber LA heads and adjustable rocker arms/mechanical lifters, requiring different length pushrods(7.342" changed to 7.16 to 7.23" for hydraulic lifters. So it is a really good idea to get some positive feedback from these guys about a good game plan for your engine/parts swap or you might waste time and money which I know I do not like to do myself, David.
